East Orange, N. J.,

assignor to Monroe CalculatingMachine Company, Orange, N. J acorporation of Delaware Application April 20, 1931, Serial No. 531,274 I4 claims. (oi. ass-144) The invention relates to registers, moreparticularly to resetting means for the dials of registers adapted forspecial computations.

As illustrated herein, the registration displayed does not consist ofthe true value of an amount entered in the digit keys or of a productthereof, but includes an arbitrary value in certain dials, whereby forinstance a registration is obtained showing even figures only in thecents to dials, in making computations in U. S. currency.

This arrangement is particularly useful in certain computationsinvolving tax assessments, wherein the total tax is to be divided intotwo semi-annual payments, the object of the special arrangement being toavoid inaccuracies involved in eliminating half cents in the semi-annualpayment. While, however, the arrangement shown and described relates tomeans for computing to the nearest even cent or other value, it isobvious that the same mechanism would be useful in registering otherarbitrary values, as for instance, in computing tax payments upon thequarter payment plan or in making various computations carried to thenearest half-cent or the nearest five centimes.

In the embodiment of the invention illustrated herein certain mechanismsare employed which are in accordance with the disclosures of U. S.patent application 337,073 filed February 2, 1929 by Britten, Jr.entitled Registering mechanism now Patent No. 1,849,448 (correspondingto French Patent 673,110) and U. S. application 379,948, filed July 2,1929 by E. F. Britten, Jr. and entitled Calculating machine, now PatentNo. 1,860,490.

The invention consists in the novel construction and combination ofparts as set forth in the appended claims.

The machine illustrated is known on the market as the Monroe calculatingmachine, disclosed in its essential parts in the Chase Patent 1,566,-650, to which reference is made for details of machine operation notspecifically forming part of the present invention.

Referring to Fig. 1 of the drawings, a line of revolutions countingdials 19 is shown, together with a parallel line of totalizer dials.Each of these totalizer dials may be connected with the adjacent dial bytens carry mechanism, or the line may consist of two series of dials,each series provided with its own tens carry mechanism. In any case, inthe special work for which the machine is designed, these dials are usedas separate accumulators, separately resettable to clear 35 therefromaccumulated values, and will be referred to hereinafter as sub-totaldials and grand total dials respectively. The ten accumulator dials atthe right hand of the line are adapted to be reset at each operation ofthe clearing 99 handle 18, and constitute the sub-total dials, the tendials at the left hand of the line being cleared only when specialmechanism is set for that purpose, and constitute the grand total dials.

An amount to be entered in the sub-total and grand total dials isintended to be set up separately at the right hand and left hand sidesof the keyboard 15, but it is to be noted that the present invention isapplicable to the machine shown in Patent 1,793,155 issued to E. F.Britten,

-Jr., on February 17, 1931 and entitled Calculating machine, this patentshowing two series of totalizer dials arranged in tandem and a set ofdigit keys adapted to control the registration of a single selectedamount simultaneously in both totalizers. Arranged parallel with therotation counting and totalizer dials is a resetting rock bar 20 havinga series of lugs 21, and also carrying slides 22, 23 and 24, each havinga series of lugs movable with said slides axially of the dials. Bar 20may be rocked rearwardly from its normal position shown in Figs. 4, 5and 6, to bring the'lugs 21 thereof, and the lugs of slide 24 into thepath of movement of stop pins arranged on the counting dials. Said baris also movable forwardly from its normal position, to bring other ofthe lugs 21, and the lugs 33, 39,

42, 45 and 48, of the slides 22 and 23, into the path of movement ofstop pins on the accumulator dials. Bar. 20 will be rocked'first in theone and then in the other direction, as abovenoted upon rotation ofcrank 18, by the means hereinafter referred to, rotation of said crankalso imparting one revolution to shaft 28, by means of the gearing 56,5'7, the accumulator wheels mounted on this shaft being carried aroundtherewith by frictional contact. When, therefore, the lugs of rock bar20 are brought into the path of the numeral wheels the rotation of shaft28 will bring the stop on the numeral wheels into contact with the lugsof the rock bar, and the numeral wheels will be held in the desiredresetting position.

Fig. 3 illustrates the position of the parts, with slides 22 and 23adjusted to reset the dials for the calculation of tax problems asfollows:

Sub-total dials 29 have their pins 30 in the path of lugs 21 of rock bar20, for clearing to 0. Between. dials 34 and any number of dials may beprovided arranged to clear similiarly to dials 29. Mills dial 31 (asshown) has a pin 32, in the path of lug 33 on slide 23, arranged forclearing to 5 duringtax computations, so that a carry to the cents dialwill occur upon an accumulation of five mills. Cents dial 34 has twosets of numerals upon its face, arranged side by side, set 35 comprisingeven figures only, ar-

ranged as shown in Fig. '7, and set 36 having the usual ten figures,running from 0 to 9. Set 35 is used during tax computations to indicatethe nearest even cent. Both of these sets of figures are arranged aboutthe dial with relation to the carry pin 3'7 so that said pin -will passthrough the cooperating carry gear, shown in dotted lines in Fig. 6, asthe figures of either series change in the sight opening of the numeralwheel carriage from a reg-.

istration of zero to a registration of the highest digit of said series,or vice versa. The gear shown in dotted lines in Fig. 6 may be a directgearing connection from a lowerto a higher order numeral wheel, or otherdelayed action carry mechanism-may be employed, both of these typesbeing well known, and both being illustrated, for example, in Patent1,462,058, issued on July 1'7, 1923 to E. F. Britten, Jr., and entitledCarry mechanism for registers.

It is to be noted of the series of even figures, that the true zero isthe figure located next to the 2, and opposite the 1 of series 36, towhich true zero position the dial must be reset during tax computations.Therefore, the resetting position related to one series isout of linewith the resetting position related to the other series, and separatestop pins 38 and 59 are provided on dial 34, pin 38 cooperating with lug39 on slide 23, for clearing the special figures to 0. Grand totaldecimal dials 40 are provided with stops 41, lying in the path of lugs42 on slide 23, for resetting to 0. Mills dial 43 (as shown) has stop 44in the path of lug 45 of slide 23, for clearing to 5. Cents dial 46 hastwo sets of numerals, arranged in the same manner as described for dial34, but is provided with five stops 4'7, any of which may engage lug 48of slide 23 for resetting to a true figure corresponding to the evencent figure last accumulated in the dial. Tens of cents dial 49, whichis similar to all of the dials located to the left thereof, will notcontact with any lug, in the above-described setting of the slides, andthe amounts accumulated on these dials will be retained as a grandtotal.

Starting from a reset position for ever" cent operation and assumingthat three is accumulated on each of the dials 34 and 46, it ill beobvious that dial 34 will show an arbitrary registration of 4, and thatdial 46 will also show an arbitrary registration greater by one than thetrue value. Also, it will be noted that the half cent dials 31 and 43having previously been cleared to 5, instead of 0, further modificationof the amount registered may be obtained. Thus, for example, a value of29.8523, would be registered as 29.8673.

Forthe convenience of the operator in reading the numerals of the centdials, movable shutters may be provided, a well-known arrangementwhereby the figures of the series not beingread will be obscured.

Fig. 4 illustrates a cam action, for moving rock bar 20 into the path ofthe stops on the dials in advance of the rotation of shaft 28, thisbeing necessary because, if dial 46 is registering a true even figure,the stop must be in position for action to retain such true figurebefore the dial is rotated. When crank 18 is rotated in a clock wisedirection (Fig. 4) shaft 50 is rotated thereby in the same direction,and a wall of cam sur-' face 51, acting upon arm 52 rocks the same aboutstud 53, a lug 54 on said arm moving rock bar 20 forward about its studs53 and 55 in advance of the action of mutilated gear 56 upon gear 5'7.In the reverse direction of movement of shaft 50, utilized in clearingthe counting dials, by means of a second pair of gears similar to gears56, 5'7, a wall of cam notch 51 will move arm 52 downwardly, and saidarm will slide on stud 53 without any action on rock bar 20. Spring 58holds arm 52 in engagement with cam notch 51.

For a normal operation, slide 23 is moved to 110 the position shown inFig. 2, moving lugs 33 and 39 into the path ,of stops 59 and 60, so that'dials 31 and 34, as well as the other dials of the right hand group,will clear to 0. In this position lugs 42, 45 and 48 will not be in thepath of the 115 pins of dials 40, 43' and 46,,and these dials will bereset or left undisturbed, according to the setting of slide 22. Whenslide 22 is positioned to clear the left hand dials, dials 43 and 46will be cleared to 0, by means of the lugs 61 and clear pins 62.

Obviously if it were desired to construct a machine for even centcalculation only, dials 34 and 46 would have one set of numerals only,and the stop pins on the dials might be arranged in simpler form. Thetwo sets of stop pins, one set active in one position of the cooperatinglugs of the slides, and the other set active in another position of theslide, corresponds with the disclosure of application 379,948,hereinbefore referred to.

It is also obvious that the half cent dials (3'1 130 and 43 might bedispensed with, ordinary dials, clearing to zero, being employed in themills order. This would give a computation of the odd cents to the nexthigher evencent.

As illustrative of the operation of the present 135 invention toeliminate mental revision of subtotals and the accumulation of errors inthe grand total dials, the following example is given:

Rate of assessment $21.79 per $1000.00

This calculation was begun with the machine in the condition illustratedin Fig. 1, except that the grand total dials were set similarly to thesub- 15(3 total dials. The amounts on the keyboard were then transferredseven times to the totalizers; the carriage shifted to the right; theamounts transferred three times; the carriage shifted, and the amountstransferred once, giving a multiplicacation by 137. Both series of dialsnow read 29.86. The carriage was then repositioned and the resettingmechanism operated, which, as will be evident from the foregoingdescription, would bring the machine into the condition illustrated inFig. 1. Multiplication by 1200 now gives the corrected or arbitraryregistration 26.16 on the sub-total dials and 56.02 on the grand totaldials.
